Self-winding

In order to accommodate months with 31, 30 and 28 days, and february 29 in leap years, a movement must have a mechanical “memory” of four years – or 1,461 days. This function requires a highly sophisticated mechanism, based on a complex system of levers and cams pivoting around their axes. This is a domain in which Patek Philippe has repeatedly leveraged its long-standing competence.

Opaline-white dial, hand-guilloched center. Fold-over clasp. Case: rose gold. Sapphire-crystal case back protected by a hinged dust cover. Water resistant to 30 m. Case diameter: 38 mm.

How to set the moonphase indicator?

A disc, decorated with golden stars and two golden moons against a blue or white background representing the sky, rotates within an aperture. The disc is cut from a wafer of corundum crystal (sapphire).

Gold was condensed onto the disc by means of a vacuum process through a photographic mask to create the shape of the moons and stars.  The aperture is cut at its upper edge in order to represent the lunar cycle.

During the first days of each lunation, the leading edge of a golden moon becomes visible as a crescent on the left of the aperture and appears to wax as it emerges beyond the curved edge of the aperture representing the lunar terminator.

Half way through the lunation, the moon appears full. It then wanes as it disappears behind the terminator on the right of the aperture.

As the moon vanishes, the second moon on the disc is ready to appear on the left.

How to set the leap year indicator

The leap year indicator informs you about the year cycle: leap year or non leap year. Leap years are identified with the Roman numeral IV or the Arabic numeral 4.
Please select a year and press "Calculate" to find the year cycle.

Attention to details
Guilloché

This age-old hand-guilloché technique is used to engrave straight or circular grooves only a few tenths of a millimeter thick, and three to four hundredths of a millimeter deep. The intersecting grooves of guilloché form a patina of endlessly varied motifs to catch and reflect the light; here, they strike out from the center in rays.
